Question

EXERCISE 9.1
1. Identify the terms, their coefficients for each of the following expressions.
(1) 5.ryz? – 3zy (i) 1 + x + x2 (iii) 4x²y2 - 4xyz? + z2
(iv) 3–pq+gr – rp (v) + - xy
(vi) 0.3a – 0.6ab + 0.5b​

Answer 1

Step-by-step explanation:

spl.1. (1) not a quadratic equation

(2). according to gener form ax²+bx+c=0.a≠0

4 is coefficient of (a) , -4 is coefficient of (b) and 2 is coefficient of c
